Weezy has been saying that Birdman has held back tens of millions of dollars from him, throughout his career. According to TMZ, "Wayne's lawyer, Howard King, filed docs saying the Cash Money honcho and Universal backdated a deal to make it look like it was signed BEFORE Young Money's deal ran out."

The outlet continued: "In docs obtained by TMZ, Wayne's camp says Universal knew that backdating the deals would screw Lil Wayne out of profits from Young Money and the artists signed under his label."

Moreover, Wayne filed documents last month that said that he would end his Young Money Records label -- which is under Cash Money Records and Universal -- if things don't get worked out with Birdman, in regards to their financial beef.

Now, it looks like Baby is making fun of Wayne's money woes. On Monday (Nov. 13), Birdman posted a picture of an expensive Louis Vuitton toilet -- They make those? -- with a shady hashtag. The post read: "I'm buyin this b**ch got to have it asap 10 bathrooms I kan s**t all day#tunechi#originalCMB." See the post below.
